* This version of the ever so popular GetQuote shows how to use the
* Axis client APIs with and without WSDL. The first flavor (getQuote1)
* will use WSDL to prefill all of the data about the remote service.
* The second one (getQuote2) will do it all manually. Either way the
* service is invoked it should produce the exact same request XML and
* of course same results.
*
* This sample supports the use of the standard options too (-p ...)
